Rigby High Innovators Triumph in National Biomass Challenge

On March 29, two student teams from Rigby High School participated in the first Pathways Student Challenge. This event, sponsored by the Department of Energy’s Feedstock Conversion Interface Consortium and supported by Battelle Energy Alliance, challenged teams to create machines that grind biomass—like wood chips and corncobs—into materials for biofuel production. Each team had a budget of $2,000.

The competition was held at the Energy Systems Laboratory at Idaho National Laboratory. Here, the machines were tested and evaluated by experts. The event aimed to identify the most effective biomass processing machine and to introduce students to practical engineering challenges. Lex Godfrey, a teacher at Rigby High School, noted the competition's role in highlighting engineering and technology careers.

The teams developed different machine designs. Team 1 designed a bulk feeder with a sensor-activated pneumatic ram to avoid clogs. Team 2 created a vertical feeder with air nozzles for efficient grinding. Both teams were advised by INL professionals, including Biomass Engineer Kristian Egan and drafter Tyler Butikofer, who provided advice but let the students lead their projects.

Both designs prioritized safety and functionality. Team 1 added a cover over the chain drive for safety, while Team 2 installed air filters and latches to reduce dust emissions. After evaluations, Team 1 won the competition. The judges considered machine performance and the teams' ability to communicate their design process and results.
